The present application is based on, and claims priority from, China Patent Application No. 202421371592.3, filed Jun. 14, 2024, the disclosure of which is hereby incorporated by reference herein in its entirety.

The present invention generally relates to a button structure, and more particularly to a button structure which is used in a game controller, improves an operating hand feeling in use, is assembled stably and lowers a cost.

A directional pad (D-pad) belongs to a standard component of a game controller. Most of the game controllers are equipped with the D-pads. The D-pad includes four push buttons with different functions, and the D-pad is used for moving in four directions which are an upward direction, a downward direction, a leftward direction and a rightward direction. A bottom of the D-pad is in contact with a metal button which is arranged on a circuit board for providing a feedback force so as to improve an operating hand feeling.

A control panel assembly for an inputting device includes a bracket with a supporting element having a supporting surface, a button cap configured to pivot relative to the bracket, and a returning mechanism configured to make the button cap offset towards the bracket. The button cap has an outer lip, and a pivoting element configured to resist against the supporting surface of the supporting element. The returning mechanism includes a hub portion of which at least one part is positioned between the button cap and the bracket, and at least one first spring. The at least one first spring has a fixing end connected to the hub portion, and a free end configured to be deflected relative to the fixing end. The free end of the at least one first spring is coupled to a first portion of the outer lip of the button cap. The game controller is equipped with the metal button of the circuit board which is combined with the D-pad to provide operating feedback so as to improve the operating hand feeling.

However, a gap between the D-pad and the metal button is apt to be caused to affect the operating hand feeling, and the metal button is more costly to be manufactured. Furthermore, the metal button which is arranged on the circuit board of the game controller has a poor rebound effect.
